在...的开始

Tetraploid embryos could be produced by electrofusion at the stage of two-cell embryos, which could develop to blastcysts fellowed by fusion of cytoplasm and nucleus and cleavage in vitro.After fusion of cytoplasm, the DNA methylation levels of the fused embryos was very high as well as two-cell diploid embryos in vivo.Then the embryos was rapiddly demethylated when the nucleus begin to fuse, resulting the lowest DNA methylation levels when the nucleus fused completely.After that, the DNA methylation levels of fused embryos were gradually increased until the blastocysts stage.However, whereas an asymmetric distribution of DNA methylation was established in an vivo-derived blastocysts with a higher methylation level in the inner cell mass than in the trophectoderm, in most vitro-derived tetraploid blastocysts, we can not detect the asymmetric distribution.

结果表明：利用电融合方法制备的小鼠四倍体胚胎在体外培养体系中经历细胞质融合、细胞核融合及细胞继续分裂发育直到囊胚期的过程，在细胞质融合的时候胚胎卵裂球同体内体外培养二倍体胚胎一样，呈现高度甲基化状态；在细胞核开始融合的时候，甲基化水平急速下降，在细胞核完全融合的时候甲基化水平达到最低点；随着胚胎继续分裂，胚胎甲基化水平逐渐增加，在囊胚期甲基化水平最高；但是囊胚期四倍体胚胎内细胞团同滋养层细胞甲基化荧光信号没有差别，这与体内体外培养二倍体囊胚内细胞团细胞甲基化荧光强度高于滋养层细胞甲基化荧光强度不同。

But beginning in the attempt, not to establish, but to evade —— not to discover a principle, but to escape a postulate —— not to settle the nature of right and wrong, but to determine what was not wrong of a particular nature,—— Casuistry went on with its dexterous refinements till it ended in so attenuating the moral features of actions, and so belying the moral instincts of Our being, that at length the conscience of mankind rose suddenly in revolt against it, and consigned to one common ruin the system and its doctors.

但在其开始的企图中，它不是在建立而是在规避，——不是在发现一条原则而是在逃避一个假定——不是在确定是和非的性质而是在行为的决定在一个特殊性质中哪些是不错的，——诡辩学就是这样用了它的巧妙的高论继续发展下去，直到它最后过分地削弱行为的道德特征，过分地诽谤了我们人类的道德本能，以致最后人类的良心突然起来反抗它，并把这体系和其博士们埋葬在一个共同的废墟中。
